How can I exclude value from

@Parcelize

? I have a class where

Bar

is 3rd party library class.

data class Foo(
  val id : Int = 0,
  val bar : Bar? = null
)

At compile time I get

Type is not directly supported by 'Parcelize'. Annotate the parameter type with '@RawValue' if you want it to be serialized using 'writeValue()'

on

Bar

. That is fine by me. I’m happy to lose that value. But no combination of

@IgnoredOnParcel

and

@RawValue

did not worked for me yet - runtime error when serializing value.

It's probably not exactly what you need, but you could do something like this:

@Parcelize
data class Foo(val id: Int = 0) : Parcelable {
    @IgnoredOnParcel
    var bar: Bar? = null
}

The error doesn't appear, even without the

@IgnoredOnParcel

annotation or just do it the old fashioned way, and implement the

Parcelable

interface yourself 🙂

Yeah that would, but then I have to make

bar

mutable

I filed a ticket for @IgnoredOnParcel... Doesn't work

@kenkyee could you share a link to the ticket?

I see, that Yan commented about my case

I guess I was pretty close with my snippet to the intended use 😂

I still don't understand why it can't work on constructor parameters, especially with data classes...
